Which of the following describes a network security measure that includes real-time monitoring and analysis?

An Intrusion Detection System (IDS) is designed specifically for real-time monitoring and analysis of network traffic. It continuously scans for unusual activities or policy violations based on predefined security rules. When it detects any suspicious activity, it generates alerts to notify administrators, allowing for immediate response to potential threats. This capability is essential for identifying and mitigating security breaches as they occur, making it a critical component of a comprehensive network security strategy.

In contrast, a traditional firewall primarily focuses on controlling inbound and outbound traffic based on predefined rules but does not provide the same level of detailed monitoring or analysis of traffic patterns. Antivirus solutions are primarily geared towards detecting and removing malware from systems and do not typically involve network monitoring. Endpoint protection encompasses a broader strategy that includes antivirus and other measures for securing devices but may not focus specifically on network traffic analysis in real-time.
